Abstract

The Eurasian Jackdaw is thought to be archetypically monogamous, but recent tagging research uncovered extra-pair copulations in the species. Here we examined extra-pair paternity (genetic monogamy) in Eurasian jackdaws breeding in the Judean Hills, Israel, at the global edge of the species range, using a set of highly polymorphic molecular microsatellites. We found roughly a sixth of nests sampled showed deviations from monogamy, more than previously found in DNA fingerprinting studies of jackdaws, suggesting a mixed mating strategy in this population. These findings support the trend of extra-pair paternity in avian species, even when social monogamy remains the rule, and highlight the importance of continued study of species throughout their geographical range.

欧亚寒鸦没有严格的一夫一妻制

欧亚寒鸦被认为是典型的一夫一妻制，但最近的标记研究发现了该物种的额外配对交配。在这里，我们使用一组高度多态的分子微卫星，研究了在以色列朱迪安山繁殖的欧亚寒鸦的额外配对亲子关系（遗传一夫一妻制），该地区处于物种范围的全球边缘。我们发现，大约六分之一的采样巢穴显示出与一夫一妻制的偏差，这比之前在寒鸦DNA指纹研究中发现的要多，这表明该种群存在混合交配策略。这些发现支持了鸟类物种中额外配对父子关系的趋势，即使社会一夫一妻制仍然是规则，并强调了在整个地理范围内继续研究物种的重要性。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
